Problem

Three particles begin at rest and pass through the potential differences shown below. • Particle 1: charge +2e+2e, mass mm, ΔV=50 V\Delta V = 50\,\text{V} • Particle 2: charge +e+e, mass 0.5m0.5m, ΔV=100 V\Delta V = 100\,\text{V} • Particle 3: charge +3e+3e, mass 2m2m, ΔV=30 V\Delta V = 30\,\text{V} Which ranking lists their final speeds from greatest to least? a) Particle 3 > Particle 2 > Particle 1 b) Particle 1 > Particle 2 > Particle 3 c) Particle 2 > Particle 1 > Particle 3 d) Particle 3 > Particle 1 > Particle 2
